Specification of Letters Patent. Application filed June 30, 1908. Serial No. 441,208.

Patented Mar. 8, 1910.

To all whom it may concern:

Be it known that I, CHARLES EDOUARD Hnmnon, a citizen of the have invented a new and'uscful Combustion- Engine, which is fully set forth in the following specification.

his i vention has for its object to ob viate the necessity cooling cylinders engines.

The characteristic feature of this invention consists in the arrangement of valves l relatively to the cylinder.

For facilitating the control of the valves l and the arrangement of water chambers in existing engines, the valves are always arranged at the side of the cylinders, and the result is that between the cylinders and the the burned gases, there is a conduit in which the said gases are compressed at the moment of their escape. I Heating results from this fact.

of internal combustion;

In the new construction the two valves are in contact with the cylinder. Fresh gasesare admitted through one of the valves, and the combustion gases escape through the other. The latter l which necessarily becomes hot, takes advantage of the cooling of the inlet valve, as the said valves are connected together by metal i cooled by a special arrangement of two fans arranged at each side of the cylinder or cyli inders. One of the fans is more powerful than the other, in order to absorb the speed acquired by the current of'air from the first, i said current of air being stopped by contact with the cylinders.

The arrangement of the cylinder valves and of the two fans is illustrated, by way of example, in the accompanying drawings, in which r- Figure l is a sectional end elevation of a cylinder of a two-cylinder engine for instance. F 2 is an elevation of a group of" two cylinders, the left hand one being shown in section. Fig. 3 is a plan, one of I the cylinders having its valves removed.

1 represents the cylinder, 2 the portion of the casing for the exhaust valve, 3 the casing for the gas-inlet valve, 4 the controlled valve for the exhaust of the gases, 5 the automatic valve or a valve which can be controlled by the admission of the gases. These valves are made of a special shape, I

r so as to do away with any resistance at the j tion of the for the exhaust and their direct line.

for the use of water for inlet and at the outlet of the gases from the cylinder.

The air current discharged by the fan 8 is discharged against and exercises a cooling effect on the cylinder, but the said air having become heated and stopped in its movement, must be impelled afresh, that being thereason why a. second fan is used which drives the said hot air away from the engine.

is a metalblade made in one piece with the cylinders and the valve supports, in order to increase the area in contact with the air-currents.

12 is the valve gear.

The operation will be clearly understood from the drawings. The gases are drawn through the valve conduit 5 behind the first fan and in front of the exhaust valve which is that which becomes hot. I

Owing to the speed of the gases passing through the valve 5, all the metal parts surrounding the same are already cooled. A portion of the said temperature is, therefore, communicated, on the one hand, by the conductivity of the metals, to the metal walls of the exhaust valve chamber and cools them, and on the other hand the current of air from the fan 8 becomes cooled in contact with the metal which constitutes the inlet valve and valve chamber for the admission of the gases, against the metal of the walls constituting the means required for the escape of the combustion gases. The fresh air current becomes heated by contact with the latter elements, but is fan. On the other hand, by means of this arrangement, the combustion: gases .do not meet any obstacle to their escape from the cylinders and escape in a straight .line in 1 accordance with the arrow 7 this air being driven 100 drawn away by the second 105 in front of the exhaust valve for the purpose Claim.
